A damage-free machining method for CFRP without feedback control systems

Yasuo Kondo, Satoshi Sakamoto

    Abstract

    A damage-free cutting method called the constantload feeding method is proposed as a high-precision machining method in carbon-fiber-reinforced plastic (CFRP) cutting. The constant-load feeding method can minimize cutting defects such as burrs and scuffing during diamond-saw cutting. In addition, there was no apparent cutting damage to the cutting surface from drilling with a high-speed steel twist drill. The cutting resistance was kept at a constant value during the entire process. The constant-load feeding can selfregulate the optimal tool feed rate to realize damagefree machining of CFRP composites without any feedback control systems based on the cutting-force.
